Figure 14.4.11 ACDMASTS Register
This read-only register shows if any DMA request is pending for each data I/O channel. A DMA
request can be pending after the software deactivates the DMAC channel or disables DMA by
ACCTLDIS register bit to complete DMA operation. In this case, write or read the sample data register
(ACAUDODAT and others) to clear the DMA request.
